ATOMIZER.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed May 2, 1917. Serial No. 165,864.

To all whom it may concern:

Be it known that I, WALTER W. Floors, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in 'Atomizers, of which the following is a' specification.

This invention relates to that class of atomizers in which the means for ejecting the spray can be oscillated about the axis of a pair of tubular arms and actuated laterally to point in various directions Theessential object of the lnvent on 1s to provide a simple and eflicient airtlght device for coupling the tubular liquid and an arms with the liquid holding receptacle.

Another object of the invention is, to provide a swinging head for ejecting the liquid in which the air conduit 1s substantially larger than the liquid conduit, so that when dense oils or other heavy liqulds are used the volume of air will effectively vaporize the liquid while it is being e ected.

The novel features of the invention are more fully described in the following specification and claims, and illustrated in the accompanying drawing, in which:

Figure 1 represents a side elevation of an atomlzer embodying this invention.

Fig. 2 is a plan view of the same on a larger scale.

Fig. 3 is a vertical detail section of the same.

Fig. 4 is a section taken along the line on w of Fig. 2.

Fig. 5 is a similar vlew showmg the coupling in a different position.

Fig. 6 is a view like Fig. 5, showing the reverse movement of the coupling.

In this drawing the letter a designates a receptacle which is adapted to contain a medicinal, perfume, or other liquid utllized for spraying. The mouth of the receptacle is provided with a cap or stopper b, havmg a boss, 0, projecting from one slde of the cap and constituting the umtary member of a coupling. The boss has bores (Z and e the first named being for the passage of the liquid, and the latter for the air. The air bore is connected to a tube f extending across the interior of the cap, leading to a nipple g projecting from the outer side of the cap. A bulb, not shown, for pumping air can be attached to the nipple. The liquid bore is connected to a tube h extending nearly to the bottom of the receptacle. The boss is also provided with segmental channels i and j concentric with the axis of the boss, the first named being a continuation of the air bore 6 and the latter of the liquid bore (Z.

A coupling member 7a is rotatively connected to the boss by means of an annular groove 0 located on the boss, and a flange 7: on the coupling member. This construction permits the coupling member to be oscillated concentrically about the axis of the boss in either direction. The coupling member is is provided with an air tube or arm m and a liquid tube it both projecting from the face of the member, and being preferably in a horizontal line with each other. One end of the air tube registers with the segmental channel 71 and the opposite end of the liquid tube n with the adjacent channel located in the boss.

A head 9 is swingingly mounted on the forward ends of the said air and liquid tubes. The ends of the tubes tend to spread and thus spring into sockets r, formed in the head. The liquid tube it connects with a small liquid conduit 5, while the air tube on registers with an air conduit t both being located in the head. The air conduit is about four times the diameter of the liquid conduit, so that a large volume of air will issue from its mouth and a small stream of liquid from the nozzle.

As indicated in Fig. 2, the nozzle end of the liquid conduit points at a right angle to the mouth of the air conduit and terminates approximately on a line with the axis of the air conduit. The air under pressure issuing from the month of the air conduit will create a suction at the nozzle, and, consequently, a vacuum in the liquid tube, thus drawing the liquid from the receptacle. The liquid when issuing from the nozzle will be instantly converted into fine spray, or vaporized by the air blowing across the nozzle, and projected a considerable distance beyond the head. In view of the fact that the nozzle is limited to a thin stream, While the air ejected is larger in volume, all the liquid will be positively atomized at the time it flows from the nozzle.

I claim:

1. In an atomizer the combination with a stopper having liquid and air supply tubes, of a coupling connected to the air and liquid tubes, liquid and air tubular arms projecting from the coupling, a head swingingly mounted on the forward ends of the arms, and means for oscillating the coupling to transmit lateral movement to the head.

2. In an atomizer the combination with a stopper having liquid and air supply tubes, of a coupling connected to the air and liquid tubes, liquid and air tube arms projecting from the coupling, a head swingingly mounted on the forward ends of the arms, the coupling being provided with segmental channels to register with the arms, and means for oscillating the coupling to transmit lateral movement to the head.

3. In an atomizer the combination with a stopper having liquid and air supply tubes of a coupling including a boss projecting from the side of the stopper and having bores with segmental air and liquid channels, a coupling member rotatively mounted on the boss, liquid and air tubular arms Qopiea 01? this patent may projecting from the latter coupling, and a head swingingly mounted on the forward ends of the arms.

4:. In an atomizer the combination with a stopper having liquid and air supply tubes, or a coupling including a boss projecting from the side of the stopper, and having bores with segmental liquid and air channels concentric with the axis of the boss, a coupling member rotatively mounted on the boss, liquid and air tubular arms projecting from the latter coupling to register with the segmental channels, and a head swingingly mounted on the forward ends of the arms.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. I
